Not only is Ohlsdorf Cemetery (Friedhof Ohlsdorf) the world's largest rural cemetery, it's one of the most important. 

Covering 966 acres and boasting 12 chapels, it's where more than 1.5 million burials have taken place in some 280,000 burial sites. 

The cemetery is also where you'll find the Hamburg Commonwealth War Graves Commission Cemetery, where more than 400 allied prisoners-of-war are buried, along with many who died in battles on German soil. 

Other notable memorials include those dedicated to victims of Nazi persecution, the Hamburg Firestorm of WWII, and members of the city's anti-Nazi resistance.
